Moules pour réservoirs
Moulds for elliptical rainwater tanks
The tanks are poured upside-down and turned by means of a vacuum lifting device. Due to the elliptical shape, the width of the tanks is smaller than the width of a similar circular tank, which brings down the transport cost.
The inner moulds are slightly conical and also hydraulically shrinkable. The outer moulds consist of 2 half sections.
To release the tank, the outer mould is first opened hydraulically, after which the hydraulic system pushes the floor upwards.
